Sonendo Reports Strong Progress Toward Profitability

---

Sonendo, Inc. (“Sonendo” or the “Company”), a leading dental technology company and developer of the GentleWave® System, today reported select preliminary financial results for the year ended December 31, 2025, and other business updates.

Select Financial Updates

• Generated $28.6 million of total revenue for the full year of 2025, including $23.4 million, or approximately 82%, from recurring sales of procedure-related consumables and services;
• Reported an increase in gross margin to 41.9% for the full year of 2025, up 460 basis points compared to 2024;
• Significantly reduced loss from operations to $13.5 million in 2025 from a loss of $29.4 million in 2024, and adjusted EBITDA2 loss to $10.4 million in 2025 from a loss of $23.0 million in 2024, driven by improved operational efficiencies;
• Significantly reduced free cash flow burn2 to $10.9 million in 2025 from $24.8 million in 2024; and
• The company expects to achieve positive free cash flow2 and positive adjusted EBITDA2 in the second half of 2026.

On November 17, 2025, Sonendo entered into a strategic collaboration with a European-based dental company and secured exclusive rights to sell high-quality products in North America. This collaboration enables Sonendo to offer a comprehensive suite of endodontic consumable products, complementing its existing portfolio solutions and enhancing its ability to meet the full range of customer needs. The company expects this strategic collaboration to bring significant cost savings to GentleWave customers, drive more demand for the GentleWave Procedure, and support Sonendo’s revenue and gross margin growth.

As the first step of this strategic collaboration, Sonendo launched FlowLogic endodontic files in the first quarter of 2026. Sonendo expects FlowLogic files to compete with the best-performing endodontic files in the industry, while being offered to GentleWave customers at a significant discount.

“I’m pleased to report continued strong execution on our path to profitability. Through disciplined operational improvements, we significantly reduced operating expenses while driving greater efficiencies across the organization. This contributed to a meaningful improvement in our adjusted EBITDA performance. At the same time, we successfully maintained our revenue base, demonstrating the resilience of our core business and the value our GentleWave Procedure continues to deliver to endodontists and their patients. More than 1.9 million patients have been treated with the GentleWave System so far,” said Bjarne Bergheim, President and Chief Executive Officer of Sonendo. “We further strengthened our portfolio by adding high-quality ancillary products. This strategic addition enables us to provide a more complete suite of endodontic consumables, which we believe will substantially lower the cost per root canal procedure for our customers—enhancing their practice economics while expanding our addressable market and supporting long-term revenue growth.”

About Sonendo

Sonendo is a commercial-stage medical technology company focused on saving teeth from tooth decay, the most prevalent chronic disease globally. Sonendo develops and manufactures the GentleWave System, an innovative technology platform designed to treat tooth decay by cleaning and disinfecting the microscopic spaces within teeth without the need to remove tooth structure. The system utilizes a proprietary mechanism of action, which combines procedure fluid optimization, broad-spectrum acoustic energy, and advanced fluid dynamics to debride and disinfect deep regions of the complex root canal system in a less invasive procedure that preserves tooth structure. The clinical benefits of the GentleWave System, when compared to conventional methods of root canal therapy, include improved clinical outcomes, such as superior cleaning that is independent of root canal complexity and tooth anatomy, high and rapid rates of healing, and minimal to no post-operative pain. In addition, the GentleWave System can improve the workflow and economics of dental practices.
